Memorial (Russian: Мемориал) is an international historical and civil rights society that operates in a number of post-Soviet states. It focuses on recording and publicising the Soviet Union's totalitarian past, but also monitors human rights in Russia and other post-Soviet states. Memorial's full name is MEMORIAL Historical, Educational, Human Rights And Charitable Society.

Along its other activities, Memorial conducts research into the history of political repression and publicizes the findings in books, articles, exhibitions, museums, and websites of its member organisations.
